Abstract (en)
Carbon fluoride solid compositions having a low fluorine-to-carbon ratio are produced by chemical vapor deposition processes. These carbon fluoride compositions have improved wettability characteristics over polytetrafluoroethylene. These compositions can be used as films, coatings on substrates, powders, and stand-alone articles. These carbon fluoride compositions are produced by energizing vapors comprised of compounds containing fluorine and carbon to cause them to degrade into fragments which are then condensed onto a substrate to form the carbon fluoride solids. These vapors can be energized by a variety of techniques, including hot filament techniques. The carbon fluoride solids find utility as films in aircraft de-icing, cookware, appliances, surgical tooling, chemical processing, gaskets, seals, diaphragms, packings, valve seats, windings, mold release components, extruder coatings, medical prosthetics, and other similar non-wetting applications.
